GitHub is slowly rolling in 2FA. Any good open source apps that will enable me to activate 2FA token on android?

Yes! I moved from aegis to it and it is much better imo.

I love that you can back it up with a file... thatway i can put it somewhere safe and can recover my logins after my phone breaks

This! I don't even have to pick up my phone... I just check the code on my smartwatch. Awesome!
